What do you expect on that hardware?. Cray performance?. You are just bashing for the sake of it. The pi is ideal for a hobby machine, not for a day to day work environment, period.
I had some initial performance problems with my RPi due to the fact I was using a gaming mouse that was causing the CPU to spike to 100% whenever you moved the mouse. I was also using SD card that seemed to periodically lag. My initial first impression was not very good either.
Once I resolved those issues I started liking the device more.
